Bought a G reg 8v gti a couple of months ago, slowly getting it sorted. Couple of electrical questions, the knock sensor wasn't fastened to the block! Fastened it back to block Doesn't look the best, testing it, there is no continuity between any of the 3 connections (I'm assuming it's a coil?) understand it act as a microphone, so should there be. Also the Hall sensor, when I got the car there is an external wire running from the connector at the distributor to the ecu. The guy said there was a break in the harness somewhere and simply ran another wire, question being is there anything else in circuit between the distributor and the ecu that has been dropped out by using the external wire?
